Utility – Patch Cleaner

When applications are installed and updated on the Windows Operating System a hidden directory “c:\Windows\Installer” is used to store the installer (.msi) files and the patch (.msp) files.

Generally these files are important as during updating, patching or uninstalling software it will use the .msi/.msp files. If you blanketly delete all the files in this folder, you will find yourself needing to rebuild windows.

Over time as your computer is patched and patched again, these installer files become outdated and orphaned. They are no longer required, but they can take up many gigabytes of data…..(click here for more information and download the nice little utility to free up space on the Windows OS Drive).
